Nature of the problem:
I have a Win TV PCI card which I use to capture digital tv. I want to put the recorded programs on to DVD to view on my home DVD. When I use DVD Movie Factory to do this I have a couple of problems.
The most serious problem is that when I add MPEG files captured using WinTV to a DVD the audio and video are out of synch. This did not happen with MPEG files that I captured using an analog TV card and Beyond TV. The MPEG file seems ok in the DVD MF preview but it is wrong on the DVD.
The only files that this does not happen with are MPEG files captured from BBC2. When I put these on a DVD the 'Do not convert compliant MPEG files' option seems to work and the files are not converted. This also speeds up the process which is what I was hoping would happen with all the MPEG files.
Any ideas on how to fix either of these problems would be much appreciated as I am about to give up on MovieFactory. I have tried a couple of other conversion programs and they do not have the audio synch problem with the files.
The MPEG files have been passed through Videredo to trim and remove adverts, but it does not seem to make any difference when I do not use Videoredo.

Project Settings
Using standard MPEG settings that best suit time of the recording and selecting do not convert compliant MPEG option.
Output format (file, DVD, VCD, SVCD)
DVD
PAL or NTSC
PAL
Error Codes (if any)
None

Problems copying MPG files captured by WINTV to DVD
All of my sync problems have been caused by corrupted MPEGs. I call it 'sneaky" corruption because the file plays-back fine. The problems don't show-up 'till I make a DVD. (Of course corruption is NOT the only thing that can cause sync problems.)
I suspect that in your case, Movie Factory is not the root cause of your particular problem.* Your digitally captured MPEG files are probably slightly corrupted. There may be some "normal" corruption due to transmission interference, etc.
For example, when they are re-coded and/or re-multiplexed with Movie Factory, bad frames are dropped without dropping the associated audio. Now you no longer have a corrupted file, but you have a sync problem. You may have better luck with another program that does not get out of sync when it hits a little glitch... I dunno... Some people have had better luck with Nero.
The MPEGs are probably being re-coded because the digital bitrate is too high for DVD. Somebody said that the broadcast bitrate was 15,000 kbps. (Or the bitrate "stamped" on the stream is too high... even if the actual bitrate is OK.) Or, it could be that the DVB audio format is not DVD compatible.
* MPEGs are not meant to be edited, and editing them with Movie Factory can cause this "sneaky" corruption that later results in an out of sync DVD. Since you are editing with VideoReDo, the editing should not be introducing the problem.

Thanks for the useful information
Doug, thanks for response. It does not solve my problem but it does seemed to be a plausible explanation. I have noticed that VideoRedo often reports Input Sequence Errors. Windows media player sometimes jumps when playing a catured MPEG plus my freeview signal is not great so I am probably getting errors.
I have found a few applications which don't seem to have this problem but I wanted to try and see if I could fix MovieFactory as I use it for other things.
Thanks
Barney

You could be dropping some frames during the capturing process.
Make sure when you capture the video it's already dvd compliant so
MF doesn't have to re-render the mpeg file.
In VideoRedo there should be an option to set the file up for MF use.
In VideoRedo re-timestamp the files.
When you record the original files if you can set the GOP's On and timestamping set to every frame because you plan to edit the mpeg2 file.
Also send an email to VideoRedo and see what their suggestions are.
VideoRedo also has a forum.
KeithM posted he is having great results with VCR2mpeg Womble mpeg editor. You may want to try that program.

Barney,
What version of DMF do you use?
Which WinTV card are you using?
Do you author and burn as 2 separate steps?
How long does it take to author to a hrad drive folder?
Which version of VRD do you use?
Input sequence errors in your files can typically be traced down and resolved.
You should post over at their forum as well.

Update on problems copying MPEG using DVD Movie Factory
Firstly thanks to all the people who replied to my post, I have found the replies very helpful in trying to resolve my problems. I have documented below what I have found out in case it is helpful to anyone else. I still have one problem which I would be grateful for any help with, see below.
I tried to use TMPGEnc to create DVD's from my files and it helped me to get a clearer understanding of why some work and others do not. The main problem reported by TMPGEnc was that 'The video bitrate was too high for a standard DVD'. In most cases this was 15 kbps and a DVD requires this to be less than 9.8Kbps. BBC2, 3 & 4 were all less than 9.8Kbps so they were treated as compliant and did not require to be re-rendered. VideoRedo has an option to change the video bitrate which seems to fix this problem.
For some of the other files I captured TMPGEnc reported that 'The resolution of 544 X 576 cannot be used for a standard DVD.' It also reports another couple of errors about the aspect ratio and framerate not being valid with this resolution. So far I have been unable to find a way in VideoRedo or any other application to quickly convert the framesize to one of the standards. So hopefully someone will be able to help me with this. Any suggestions gratefully received.
Thanks

I also have a Hauppauge PCI PVR 350 card. I tend to record using WinTV2000 and then edit with Womble.
(For those who don't know - The Hauppauge card only records to MPEG)
http://www.womble.com/
I finish off by making my DVD with DVD Workshop 2.
Standard Video Editors do tend to produce out of synch issues with MPEG files especially if you try to insert transitions. Womble is a purpose built MPEG editor and has more functions than VideoRedo (I own both).
Neither MPEG editor has DVD authoring capabilities
As you say, capture to the highest available bit rate commensurate with the length of the program being recorded.
One last thing, Please update your profile with your system details. (It shouldn't really make much difference to this issue as the Hauppauge cards have built in (hardware) MPEG encoders.)
